Rather than mucking around with flight models and creating new aircraft, how about just figuring out how to fly the plane? Those speeds were met under certain conditions by a qualified test pilot, and in normal combat those speeds were rarely achieved. You can also match the speed if you practice, experiment and research. The Crimea map has close to standard conditions, so it will probably give you better numbers. To go to these speeds use 100% power. Be sure the rudder and elevator are trimmed. The "ball" must be centered, and the plane should maintain altitude without input from you. Adjust mixture, supercharger, and boost as necessary. The boost for some planes will not do anything at lower altitudes except for cooking your engine (Using boost or WEP in the P-51 is one example-it is totally useless on takeoff and at lower altitudes) For some planes you cannot simply apply WEP and be done. For these planes, lower power to 80% apply boost, then push the throttle to 110%. This way you won't overheat as quickly. If you go fast enough you won't need the radiators open at all anyway. Use the elevator as minimally as possible. The plane does what the manual says it will do, so don't start fiddling around just because it's a little too hard to get there.
